I would like to know what bluetooth you use with the Hero. I use one most of the time. I've been through several. I've been using a Blue Ant Z9i for the last 15 months so it moved from my Instinct to the Hero three months ago. Just wanting to change I purchased a Plantronics Voyager Pro a few weeks ago. It was very comfortable despite it's size. The main problem was that the incoming call quality was muffled and boxy. After four days of disappointment I returned it to the Sprint store for a refund. Blue Ant is bringing out the T1 next month which streams GPS and other functions through the headset. It looks promising. So what do you use? Thanks, TC.
